Warn if timestamp updated_at field uses incompatible timestamp

[gshank]

resolves #10234

Problem

Snapshot tables use the 'get_snapshot_time' macro, which may be incompatible with the data type of the field specified as the 'updated_at' field, causing unexpected results.

Solution

Warn if the two sources of timestamp columns have different data types.

Ideally we'd have CI for this, but for now let's ensure we're using 5.26.1 if possible to generate the protos: #10456

Small note on core/dbt/events/core_types_pb2.py, otherwise looks good!

The backport to 1.8.latest failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-1.8.latest 1.8.latest
# Navigate to the new working tree
cd .worktrees/backport-1.8.latest
# Create a new branch
git switch --create backport-10352-to-1.8.latest
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 c28cb92af51d7f2cb27618aeb43705ba951aa3ef
# Push it to GitHub
git push --set-upstream origin backport-10352-to-1.8.latest
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-1.8.latest

Then, create a pull request where the base branch is 1.8.latest and the compare/head branch is backport-10352-to-1.8.latest.
